Description

Glasses capable of adjusting optical center distance according to pupil distance

Technical Field

The utility model belongs to the technical field of glasses design, and particularly relates to glasses capable of adjusting optical center distance according to pupil distance.

Background

Presbyopia is the phenomenon in which, with age, the accommodative ability of the eyes decreases, making it difficult to see things at close distances. Generally, all people begin to appear around the age of 40-45, and the degree of presbyopia increases with age, generally increasing at a speed of deepening 50 degrees every 5 years.

The pupil distance is the distance between the centers of the pupils of two eyes when the sight lines of the two eyes are in an orthophoria or parallel state. The presbyopic glasses need to measure the pupil distance besides the degree; if the testing of the pupil distance of the glasses is inaccurate or the optical center distance of the lenses is not matched with the pupil distance, the scenery seen through the lenses is deformed, distorted and blurred.

Common glasses in the existing market can not adjust the interpupillary distance and can not change the lenses, so that the glasses have to be changed when the presbyopia degree of a user changes.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The glasses capable of adjusting the optical center distance according to the interpupillary distance as shown in figures 1-4 comprise a bridge 1, a nose pad 2, temples 3 and lenses 4. A T-shaped hollow guide chute 11 with scale marks is arranged in the bridge 1, and the T-shaped hollow guide chute 11 is arranged along the length direction of the bridge 1 and penetrates through the front end face, the rear end face and the lower end face of the bridge 1.

The T-shaped hollow guide chute 11 is embedded with a sliding block 12, a first through hole 121 is arranged in the sliding block 12, a fastening piece 13 and an abutting piece 14 are arranged in front of and behind the bridge 1 respectively, the abutting piece 14 and the fastening piece 13 are clamped on two sides of the bridge 1 through screws, the screws penetrate through the first through hole 121 in the sliding block 12, and the lens 4 is clamped between the fastening piece 13 and the abutting piece 14.

Rubber pads 141 are embedded on the end surfaces of the abutting pieces 14 and the fastening pieces 13, which are in contact with the lenses 4.

The both ends of the bridge 1 are equipped with grafting portion 15, and the end of this grafting portion 15 is equipped with second through-hole 16, is equipped with adapter sleeve 5 between mirror leg 3 and the bridge 1, and the one end of this adapter sleeve 5 is equipped with the spliced eye 51 with grafting portion 15 looks adaptation. The other end of the connecting sleeve 5 is provided with a hinge part 52, and the tail end of the hinge part 52 is arc-shaped and is hollowed out to be communicated with the inserting hole 51.
